Eye vitamins for older people: complex guide

Section 1: Age -related vision changes and the need for vitamins

With age, our eyes undergo natural changes, which can lead to visual impairment and increased risk of developing various eye diseases. These changes are due to a number of factors, including:

  • Reducing elasticity of the lens: This leads to presbyopia, or age -related farsightedness that makes it difficult to focus on close objects.
  • Deterioration of muscles that control the pupil: The pupil may not adapt so quickly to changes in lighting, causing discomfort when moving from a light room to dark.
  • Reducing the number of sticks and cones in the retina: This can lead to a deterioration in night vision and color perception.
  • Weakening of antioxidant protection: Free radicals formed in the process of metabolism can damage the eye cells, contributing to the development of cataracts and age -related macular degeneration (VMD).
  • Reducing the blood supply to the eyes: This can lead to a deterioration in the nutrition of tissues of the eye and an increase in the risk of the development of glaucoma and other vascular diseases of the eyes.

Given these age -related changes, maintaining the health of the eyes with the help of proper nutrition and taking vitamins becomes especially important for the elderly. Vitamins and minerals play a key role in protecting the eyes from damage, improving visual function and reducing the risk of eye diseases.

Section 2: Key Vitamins and Minerals for Eye Health

There are a number of vitamins and minerals that have proven their effectiveness in maintaining the health of the eyes and reducing the risk of developing age -based eye diseases. These include:

  • Vitamin A (Retinol): Vitamin A is necessary for the normal functioning of the retina, especially sticks responsible for night vision. Vitamin A deficiency can lead to a deterioration in night vision, dry eyes and even photophalmia (drying of the cornea). Sources of vitamin A: liver, fish oil, carrots, sweet potatoes, spinach, cabbage.

  • Vitamin C (ascorbic acid): Vitamin C is a powerful antioxidant that helps protect the eyes from damage caused by free radicals. It also plays an important role in the formation of collagen necessary to maintain the structure of the cornea and the lens. Studies have shown that vitamin C consumption can reduce the risk of cataracts and the VMD. Sources of vitamin C: citrus fruits, strawberries, pepper, broccoli, kiwi.

  • Vitamin E (Tokoferol): Vitamin E is another important antioxidant that protects the eye cells from oxidative stress. It also helps to improve blood supply to the eyes and reduce the risk of cataracts. Sources of vitamin E: vegetable oils (sunflower, olive, corn), nuts, seeds, avocados, spinach.

  • Lutein and Zeaxanthin: These carotenoids are powerful antioxidants, which are concentrated in the macula (central part of the retina), protecting it from damage caused by blue light and free radicals. Studies have shown that the consumption of lutein and zeaxanthin can reduce the risk of EMD and cataracts. Sources of Luthein and Zeaksanthin: spinach, cabbage, broccoli, corn, eggs.

  • Zinc: Zinc plays an important role in the transportation of vitamin A from the liver to the retina. It is also a component of many enzymes involved in protecting the eyes from oxidative stress. Zinc deficiency can lead to vision of vision and increased risk of the development of the VMD. Sources of zinc: oysters, red meat, poultry, beans, nuts, whole grain products.

  • Omega-3 fatty acids (DGK and EPK): Omega-3 fatty acids, especially daily-zahexenoic acid (DHG), are important components of cell membranes in the retina. They help to improve visual function, reduce the risk of dry eyes and EMD. Sources of omega-3 fatty acids: fatty fish (salmon, tuna, sardines), linseed seed, chia seeds, walnuts, fish oil.

  • Selenium: Selenium is an antioxidant that works in synergy with vitamin E to protect the eyes from damage to free radicals. He also plays a role in maintaining the health of the lens. Sources of Selena: Brazilian nuts, tuna, beef, bird, whole grain products.

Section 3: Eye diseases associated with deficiency of vitamins and minerals

The deficiency of certain vitamins and minerals can increase the risk of developing various eye diseases, including:

  • Age macular degeneration (VMD): VMD is the main reason for loss of vision in people over 50 years old. It is characterized by damage to the macula, the central part of the retina responsible for acute vision. The deficiency of lutein, zeaxantin, vitamin C, vitamin E and zinc can increase the risk of EMD.

  • Cataract: Cataract is a clouding of the lens of the eye, which leads to a deterioration in vision. Antioxidants, such as vitamin C, vitamin E and selenium, can help slow down the development of cataracts, protecting the lens from oxidative stress.

  • Dry eyes: Dry eye occurs when the eyes do not produce enough tears or when tears evaporate too quickly. The deficiency of omega-3 fatty acids and vitamin A can contribute to the development of dry eyes.

  • Glaucoma: Glaucoma is a group of diseases that damage the visual nerve and can lead to blindness. Although glaucoma is often associated with increased intraocular pressure, oxidative stress can also play a role in its development. Antioxidants, such as vitamin C and vitamin E, can help protect the visual nerve from damage.

  • Diabetic retinopathy: Diabetic retinopathy is a complication of diabetes, which damages blood vessels in the retina. Blood sugar and taking antioxidants can help slow down the progression of diabetic retinopathy.

Section 4: Recommendations for taking vitamins for the eyes for older people

It is important to understand that vitamins and minerals are not a cure for eye diseases, but they can play an important role in maintaining the health of the eyes and reducing the risk of developing these diseases.

  • Get vitamins and minerals from food: The best way to get the necessary vitamins and minerals is a balanced diet rich in fruits, vegetables, whole grain products, low -fat protein and healthy fats.

  • Take multivitamins: If you do not get enough vitamins and minerals from food, consider the possibility of taking polyvitamins. Choose polyvitamins specially designed for the elderly, as they contain the necessary nutrients in optimal doses.

  • Consider the possibility of taking specialized eyes for the eyes: If you have a risk of developing eye diseases, such as VMD or cataracts, your doctor can recommend taking specialized eyes for the eyes containing lutein, zeaxantin, vitamin C, vitamin E and zinc.

  • Consult a doctor: Before you start taking any vitamins or additives, be sure to consult a doctor, especially if you have any chronic diseases or take any medicine. The doctor can help you determine what vitamins and minerals you need, and prescribe the correct dosage.

  • Observe the dosage: Do not exceed the recommended dosage of vitamins and minerals. Too high doses of some vitamins can be harmful to health.

  • Be careful with interactions: Some vitamins and minerals can interact with medicines. Be sure to inform your doctor about all the vitamins and additives that you accept.
